' Claims.

This application is a continuation-in-part ofapplication, Serial No. 708,740, filed November 8 1946, now abandoned. j The invention relates to combing machines, and has for its'primary object the provision of an improved detaching roll drive or motion of such simplicity, compactness and organizationas to be capable of operation with a minimum of vibration and effort, and hence, at high speeds. A further object, contributing to the same general result, is the elimination of play or back-lash such as has characterized prior constructions. I

With the foregoing and other objects and advantages in view, as will presently appear, the invention comprises the combinations and arrangements hereinafter described with reference to the accompanying drawings, which exemplify a present y preferred form of the invention. In the drawings:

Fig. 1 is a diagrammatic plan view of a comber, showing the preferred location of the improved detaching roll drive;

Fig. 2 is a broken out, elevational view looking toward the right-hand end of the comber of .Fig. 3 is a vertical section on the line 33 of J I Fig. 4 is a top plan view of the drive (portions of thefhousing walls being removed'to expose the parts); and f 1 Figs. 5. 6 and 7 are ,yertical sections on the lines 5 5, .6 8. and 'I'I, respectively, of Fig. 4 (thebackground being omitted in FigsQG and 7).

In Fig. '1 a comber I, including end frame members 2 and 3, is shown in more or less standard,

general arrangement, a draw box a and coiler 5 being indicated at the left. At'the right, there is indicated a housing 6 which encloses the, roll ber} and-the outer wall acover removably secured to the surrounding, housing wall 9. While it is. by no means essential that the drive .be wholly enclosed, it is a feature of this preferred form that the organization isadapted to permit the I mechanism .to be housed, as indicated, in what serve asan oil bath enclosure, sothat adequate lubrication at all times is assured, without danger of the lubricant'spreading to'other parts of the comberand'so'iling the stock. In Figs. -2 and 3 1 application February 19, 1949, sea visas (o1. 19-11s) v there is shown a sight gauge So, by which the oil level is indicated.

' The drive shaft for the motion may be the usual comb cylinder shaft I0, at least a portion of which extends between the walls I, '8. In this instance, the shaft I0 is journaled in these walls andextends beyond the outer wall where/on its freeend, it carries a drive pulley I0a. Keyed to'shaft l0 between-walls I, 8'is adrive gear I I which meshes with the teeth IZ 'of a compound gear I3, sometimesfor convenience referred to herein as the first driven gear. Gear I3 is mounted on and, in this instance, free to rotate upon, a second shaft I4 which, like the drive shaft, has at least a portion of its length extending between the walls I, 8 and preferably, as shown, journaled in those wallsand extending beyond the outer wall. In the present embodiment, shaft I4 serves as and is sometimes referred to hereinas a rock shaft. i

The teeth IT of compound gear I3 mesh with the teeth I8 of a planet gear member, such as compound gear I 9, which is supported 'by a planet stud 20. The planet stud is, inturn, supported by a p1anet arm 2| which is mounted on and, in this instance, secured to rock shaft I i. The teeth 22 of the planet gear member mesh with a gear 23," someti nes'referre'd to herein as the second driven gear, which is'also mounted on shaft I4. Gear 23, which'serves as the roll drive gear, meshes with a pinion 24 secured to the shaft 25 of bottom detaching roll 26. In this instance, as is common, a second bottom detaching rol12I is indicated, its shaft 28 carrying-a pinion 29 which is driven from'pinion 24 through a longtooth idler 30 carried by shaft 3 I. It will be understood that, as usual, the bottom detaching rolls 26,2"! cooperate withupper detaching rolls, the latter being indicated in dotted outline in Fig. 2, and

"tively to driven gears I3, '23. shown as comprising a wheel 32 incorporating a cam track generally designated 33; and running in the cam track is a cam roll 34, stud-supported in the end of a crank arm 35 secured to rock shaft I4. Oscillation of rock shaft I4 by the cam track 'andcani rollres'ults in oscillationof planet arm 2| and o compound gear l9 about the axis of roclcshaftfllll the described mechanism constituting' a planetary drive from gear II to the 3 detaching rolls and adapted, as the result of the orbital movement imparted to compound gear 19, which is the planet of the system, to drive the detaching rolls alternately forward and backward and at speeds determined by the shape of the cam. As will be recognized, the compound form of gears l3 and !9 provides appropriate re duction.

As shown more particularly in Fig. 5, the cam track is more or less kidney-shaped, including a concentric portion 36 extending through slightly more than half the circumferential length of the track; and a re-entrant portion consisting of straight stretches 31, 38 merging at a point 39 of minimum radius and at their outer ends merging smoothly into the ends of the concentric portion. The direction of rotation of shaft in and cam track 33 is indicated by the arrows in Figs. 5, 6 and '7.

By reason of the fact that the motion or drive consists of a simple train of components, which can be very closely spaced and which can be well supported immediately on both side by the adiacent walls 1, 8, a high degree of balance and freedom from whip and vibration are achieved. 1:

Also, by mounting all of the gear components between the walls and the cam and crank oscillating mechanism on the outside side of the outer wall, the indicated advantages of adequate lubrication and cleanliness are achieved, while permitting the timing of the motion (which is changed by adjusting the cam track relatively to the follower) .:to be adjusted without in any way disturbing the rest of the motion.
